When interfacing with APIs that expect unix-style async I/O, it is
useful to be able to tell in advance whether a read/write is going to
block. This adds new interfaces GPollableInputStream and
GPollableOutputStream that can be implemented by a GInputStream or
GOutputStream to add _is_readable/_is_writable, _create_source, and
_read_nonblocking/_write_nonblocking methods.
Also, implement for GUnixInput/OutputStream and
GSocketInput/OutputStream

g_cancellable_create_source() returns a GSource that triggers when its
corresponding GCancellable is cancelled. This can be used with
g_source_add_child_source() to add cancellability to a source.
Port gasynchelper's FDSource to use this rather than doing its own
cancellable handling, and also fix up its callback argument order to
be more normal.

Add support for passing the full contents of the environment to the
primary instance (by storing it in the platform_data) when
G_APPLICATION_SEND_ENVIRONMENT is in the flags.
These functions are meant to replace the read_until() flavour, with the
following improvements:
- consistency between the synchronous and asynchronous versions as to
if the separator character is read (it never is).
- support for using a nul byte as a separator character by way of
addition of a length parameter which allows stop_chars to be treated
as a byte array rather than a nul-terminated string.
The read_until() functions are not yet formally deprecated, but a note
has been added to the documentation warning not to use them as they will
be in the future.
This is bug #584284.

Bug #617691.
Previously if a GSocketConnection had a blocking GSocket, it would
sometimes block during asynchonous I/O, and if it had a non-blocking
socket, it would sometimes return G_IO_ERROR_WOULD_BLOCK from
synchronous I/O. This fixes the connection to not depend on the socket
state.

- Make GCredentials instance and class structures private so it can't
be subclassed and we don't have to worry about ABI compat
issues. This also allows us to get rid of the GCredentialsPrivate
struct.
- Add a GCredentialsType enumeration that is used whenever exchanging
pointers with the user. This allows us to support OSes with
multiple native credential types. In particular, it allows
supporting OSes where the native credential evolves or even changes
over time.
- Add g_socket_get_credentials() method.
- Add tests for g_socket_get_credentials(). Right now this is in the
GDBus peer-to-peer test case but we can change that later.
- Move GTcpConnection into a separate gtk-doc page as was already

This adds a GApplication object to GIO, which is the core of
an application support class, supporting
- uniqueness
- exporting actions (simple scripting)
- standard actions (quit, activate)
The implementation for Linux uses D-Bus, takes a name on the
session bus, and exports a org.gtk.Application interface.
Implementations for Win32 and OS X are still missing.
add GSimplePermission, a trivial const implementation of GPermission
can-request and can-release are always false for this implementation and
the value of 'allowed' is decided at construction.
This uncovered a bug in name watching if the name wasn't activatable.
Also provoked the need for on_connection variants of g_bus_watch_name
(added g_bus_watch_proxy's variant as well).
This makes it possible to use the cached properties mechanism even if
constructing the proxy with the DO_NOT_LOAD_PROPERTIES flag.
This is useful for cases where you obtain the and track object
properties out-of-band. For example, in udisks, the plan is to have
something like this
Manager.GetObjects (out ao paths, out aa{sa{sv}} all_properties);
Manager.ObjectAdded (o path, a{sa{sv}} all_properties);
Manager.ObjectChanged (o path, a{sa{sv}} all_properties);
Manager.ObjectRemoved (o path, a{sa{sv}} all_properties);
E.g. the first GetObjects() call will return *all* data about *all*
exported objects. Further, this way a client will only need to listen
these three signals (three AddMatch) on the Manager object and it will
never need to do GetAll() etc (e.g. can use DO_NOT_LOAD_PROPERTIES).
(Of course this only works if the client is interested in all
objects... while this is true for udisks it is generally not true for
other D-Bus services).
Also use expected_interface to check for programming errors.
Lots of people been suggesting this. We still use MethodInvocation /
method_invocation for handling incoming method calls so use call()
instead of invoke_method() helps to separate the client and server
facilities. Which is a good thing(tm).
There are apparently two incompatible ways of naming abstract sockets:
pad the sockaddr with 0s and use the entire thing as the name, or else
don't, and just pass a shorter length value to the relevant functions.
We previously only supported the former method. Add support for the
latter.
Also correctly handle "anonymous" unix sockaddrs (eg, the client side
of a connection, or a socketpair() socket), and add unix domain socket
support to the socket-client and socket-server test programs to make
sure this all works.

This patch only adds the function. The function is a NOP.
See the API documentation for a rationale.
Part of: Bug 591388 - number of GCancellables available is too limited
For details, see bug 587482. The new api:
- Provide new _with_operation() variants of all unmount and eject methods
- Add GMountOperation::show-processes signal
- this can be used to show processes blocking an unmount operation
- Deprecate all unmount and eject methods
- Add g_drive_can_start_degraded() method
- this is to avoid auto-starting degraded drives
- Make g_drive_stop() resp. g_file_stop_mountable() take a GMountOperation
- these ops were recently added and not yet public API so it's fine
to change how they work
- Provide a way to poll mountable files, e.g. g_file_poll_mountable()
- Add some missing file attributes for mountable files
- G_FILE_ATTRIBUTE_MOUNTABLE_UNIX_DEVICE_FILE
- needed for the GDU Nautilus extensions to format a volume
- G_FILE_ATTRIBUTE_MOUNTABLE_CAN_START_DEGRADED:
- mimics g_drive_can_start_degraded()
- G_FILE_ATTRIBUTE_MOUNTABLE_CAN_POLL:
- mimics g_drive_can_poll_for_media()
- G_FILE_ATTRIBUTE_MOUNTABLE_IS_MEDIA_CHECK_AUTOMATIC
- mimics g_drive_is_media_check_automatic()
Add API for starting/stopping drives. This new API will enable
GVolumeMonitor and GVfs implementations to add support for the
following features
1. Powering down external hard disk enclosures / drives
2. Starting/stopping multi-disk devices (such as RAID/btrfs/ZFS)
3. Connecting/disconnecting iSCSI devices
4. Reacting to the user pressing e.g. the "remove drive" button on
a IBM/Lenovo Ultrabay: http://www.thinkwiki.org/wiki/Ultrabay
See the bug for the corresponding GVfs and Nautilus changes.
The whole protocol name thing is pretty weird. The getprotobyname functions
seem to only specify one mapping for name <-> ids, so all families/types
must use the same values. Plus the values used for the protocols are
standardized by IANA, so are always the same.
So, we drop using names for protocols, intead introducing an enum with
a few commonly availible and used protocols.
Higher-level wrappers around GResolver. GSocketConnectable provides an

There are race conditions when connecting and disconnecting from the
